31 October 2018: Researchers at Princeton University and the Scripps Institution of Oceanography published a study that warns that global warming may be happening faster than scientists have previously estimated.
The study, published in Nature, suggests that these findings may mean that emitted greenhouse (GHG) gases have generated far more heat than scientists originally predicted, meaning that the Earth is more sensitive to carbon dioxide than scientists thought.
The study titled, ‘Quantification of Ocean Heath Uptake from Changes in Atmospheric Oxygen and Carbon Dioxide Composition’, assesses ocean warmth using “a whole-ocean thermometer” to measure carbon dioxide and atmospheric oxygen, both of which increase as the ocean warms and releases gases.
In other words, the researchers measured the amount of carbon dioxide and oxygen lost by the oceans, and then calculated the amount of warming needed to explain that change in gases.
Previous studies have estimated ocean temperature using…
